Abstract: A technique facilitates drilling operations by combining a conductor with a conductor sharing offset shoe system. The conductor sharing offset shoe system protects against collision of boreholes by properly positioning and/or orienting a drill string during drilling of boreholes through the conductor. The conductor sharing offset shoe system may comprise a bullnose disposed at a lower end of the shoe system and an upper guide member disposed at an upper end of the shoe system with a guide opening sized to receive the drill string therethrough. A guide tubing extends from the guide opening into the bullnose to guide the drill string during drilling of a borehole. The guide tubing is sized to preserve sufficient space for accommodating movement of the drill string through the conductor sharing offset shoe system externally of the guide tubing during drilling of another borehole.

Abstract: An apparatus for introducing a drop ball into a well is provided. In one embodiment, the apparatus includes a wellhead assembly mounted over a well and a ball launcher for routing a drop ball into the wellhead assembly. The ball launcher includes a fluid conduit coupled to the wellhead assembly and a pilot ball disposed in the fluid conduit. The ball launcher also includes a stop positioned in the fluid conduit to prevent movement of the pilot ball past the stop while allowing movement of the drop ball past the stop and into the wellhead assembly. Additional systems, devices, and methods are also disclosed.

Abstract: A system for holding a tubular string in a well is provided. In one embodiment, the system includes a cartridge having a body that can be installed within a wellhead spool attached to a well, and the cartridge includes slips and a setting ring that are disposed within a bore of the body. The slips and the setting ring are retained within the bore of the body and are axially movable within the body such that, when installed within the wellhead spool, the slips are retained in a retracted position when the setting ring is in a first axial position within the body and the slips contract inwardly when the setting ring is moved to a second axial position. Additional systems, devices, and methods are also disclosed.
